Reflections on RSNA 1981

The annual meeting of RSNA has provided the following points. Computed tomography and ultrasound have become well established in routine medical care. Digital technology is becoming increasingly important in many fields of medicine like in radiology (digital substraction angiography), physiologic and clinical information system. Nuclear magnetic resonance (NMR) recently recognised as a more important diagnostic tool may become the technique of choice for the early diagnosis of multiple sclerosis and high pressure hydroencephalus. It is also usefull for the diagnosis of cardiac and vascular diseases.
